SCORING ATTACHMENT FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented June 2%, 1915.

Application filed July 9, 1913. Serial No. 778,014.

To all whom it may concern Be it known that I, EDWARD L. KINAsT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Scoring Attachments for Printing-Presses, of which the following is a description.

My invention belongs to that general class of devices known as scoring attachments for use on printing presses, and relates particularly to a combined scorer and gripper, or frisket finger.

The invention has among its objects the production of a device of the kind described that is simple, convenient, eflicient, durable, adjustable and satisfactory, and that may be used wherever found applicable.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described,

and more particularly pointed out in the claims. 7

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a view in elevation of the device, and a portion of the rocking gripper bar. Fig. 2 is substantially a side elevation of the same. Fig. 3 is a cross sectional view taken substantially on line 3, 3 of Fig, 2. Fig. 4; is a similar sectional view showing the same in an adjusted position. Fig. 5 is a cross sectional view of a portion of the same reversed, and Fig. 6 is a sectional view of a modified form.

Referring to the drawings, in which the preferred form of my device is shown, t may be mentioned that the device consists in a combined scorer and gripper finger, which may be reversed and used as a sheet gripper or frisket finger only, if it is so desired. The device is attached to the usual rocking bar or gripper finger bar 1, which is suitably secured to the printing press and operated in any desired manner. Detachably and adjustably secured to the bar 1 is the finger 2, preferably provided with an enlarged and flattened end 3, adapted to be positioned on the bar 1. The finger is secured to the bar by a bolt 5 and nut 4c, or equivalent means, the bolt preferably extending through a slot in the bar 1. In order to prevent the finger end from moving transversely, or that is, its pivoting on the bolt, the slot 7 is arranged in the bar and the finger end 3 provided with a flange 6, which is adapted to be posiing which is required or desirable.

tioned therein. The device shown is also preferably provided with an oppositely ex tending lateral flange 8, adapted to fit into the slot 7 when the bar is reversed, as is hereafter described.

Upon one face or side of the finger 2 is a scoring ridge or head 9, which is brought to an edge of the desired degree of sharpness. The finger is also provided on the opposite face or side with a detachable part 10, the same being secured in place by screws 11, or the equivalents for the purpose. When it is desired to increase the thickness of the finger, the part 10 may be separated and any desired number of sheets of paper, wood or metal 12, or the equivalent, inserted between the two parts. The number of sheets, of course, depends upon the thickness of the same and the desired thickness of the finger, the desired thickness of the finger, of course, depending upon the depth or degree of scor- In the modified construction shown in Fig. 6, the detachable back 15 is provided with a groove 17, corresponding in contour with the head 9, so that when part 2 is turned around and the screws 16 tightened down, the finger is reduced in thickness the depth of the bead 9, and -may be used as a gripper only.

In operation, assuming that the device is in the position as shown, when the platen is moved up to the bed the .soorer carried by the gripper bar is positioned between the two, and the bead or ridge 9 is impressed into the paper, whether it may be light or heavy cardboard stock or the like. (I have not considered it necessary to illustrate the platen and bed of the press, as these parts are well known to those skilled in the art, and the operation of the press is familiar to all.) The scoring finger may be moved along the bar 1 so as to score at any desired point. If it is not desired to use the scorer, the back part 10 may be detached and the finger 2 reversed or turned around, for ex ample, as indicated in Fig. 5, so that the flange 8 engages in the groove 7. By removing the detachable back, the thickness of the scorer is so reduced that there is no scoring of the paper. With a scoring device of this kind it will be noted that there is no printing of the scorer upon the material, since the scorer is never inked when the type is inked, as is the case where a scorer is carried by the bed. The scorer may be increased or decreased in thicknesses by adding. or re moving paper between the two parts, so as to score the desired depth, depending upon the material in the press. The device is exceedingly simple, in fact so simple that it cannot possibly get out of order, nor does it require extensive time to adjust it, either in its position on the press or as to depth of scoring. 7

Having thus described my invention, it is obvious that various immaterial modifica- "ions may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the eXact form, construction, arrangement or combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is p 1. A device of the kind described, comprising the combination of a finger adapted to be secured at one end to the rockingbar, and provided with a ridge on one face thereof with a cooperating back plate formed to lie upon the opposite face of the finger, and means for detachably securing the same together.

2. A device of the kind described, comprising a finger bar constructed with a V- shaped extension on one face thereof, and arranged to be detachably connected to a rocking shaft, in combination with a 00- operating back plate, provided with a groove bination with a cooperating finger, provided at one end with a T-shaped extension constructed on either side to be set in the groove and a bolt hole therethrough, one face of the finger being provided with a V-shaped ridge a cooperating back plate adapted to lieagainst the opposite face of the finger, and means for detachably securing the two together.

4. A device of the kind'described, co prising-a finger bar constructed at one end with a T-shaped head and a bolt hole therethrough,'and provided a V-shaped ridge on one face thereof, in combination with a cooperating back plate constructed with a slot adapted to receive the V-shaped ridge when the finger bar is reversed, and means for securing the two together. V V In testimony whereof, I have hereunto signed my name in the presencelof two subscribing witnesses.
